Where is internal iliac vein?
The internal iliac vein, also known as the hypogastric vein, is a short vessel found in the pelvis. It arises from several smaller veins just above the greater sciatic foramen.
What receives blood from the internal iliac vein?
The internal iliac vein receives the middle rectal, obturator, lateral sacral, inferior gluteal, and superior gluteal veins as tributaries. The obturator vein enters the pelvis by way of the obturator foramen, where it takes a posterosuperior route along the lateral pelvic wall, deep to its artery.
Why is the internal iliac vein important?
The vascular system of the uterus is based on the uterine artery from the internal iliac or hypogastric artery and on the ovarian artery from the abdominal aorta. These vessels give origin to an important anastomotic trunk with a typical circular disposition.
What causes iliac vein blockage?
The cause of obstruction or narrowing may be due to blood clotting (thrombosis) or non-thrombotic as in May-Thurner syndrome. A deep vein thrombosis can result in complete or partial blockage, whereas narrowing is typically due to compression from the spine, or more rarely a cyst, growth, or cancer.
What is the big vein in your thigh?
A large blood vessel of the thigh, the femoral vein is a major pathway in which blood from the lower limbs travels on its way back to the heart. It is sometimes called the superficial femoral vein (in contrast with the deep femoral vein).
Where does common iliac vein drain?
The left and right common iliac veins come together in the abdomen at the level of the fifth lumbar vertebra, forming the inferior vena cava. They drain blood from the pelvis and lower limbs.
How deep is the iliac vein?
The SCIA emerges about 3 cm under the inguinal ligament from the femoral artery and runs to the anterior superior iliac spine. The planned flap design is transduced to the region. Here, the caudal border should be less than 5 cm caudal from the inguinal ligament. The common size is 10 × 20 cm.
Where does blood go after the common iliac vein?

What is iliac vein stenting?
When an iliac vein narrowing (stenosis) is discovered, this can be treated with placement of a stent in the vein. The stent is inserted into the compressed iliac vein by a needle stick approach in the groin.
